(1) If the preliminary estimated costs of acquiring the data and information to prepare an EIS total more than $2,500, the department must notify the applicant that a fee must be paid and submit an itemized preliminary estimate of the cost of acquiring the data and information necessary to compile an EIS. The applicant must also be advised that a notarized and detailed estimate of the cost of the project being reviewed in the EIS must be submitted within 15 days after receipt of the request. In addition, the applicant must be asked to describe the data and information available or being prepared by the applicant which can possibly be used in the EIS. The applicant may indicate which of the department's estimated costs of acquiring data and information for the EIS would be duplicative or excessive. The applicant must be granted upon request an extension of the 15 day time period of submission of an estimate of the project's cost and a critique of the department's preliminary EIS data and information accumulation cost assessment.
